Hello there, Pru1.
Let me help you in matching the bank transactions. It's great that you're able to make sure that the dates and bank account are correct.
One possible reason why we're unable to match them is that the transactions you recorded in QuickBooks Online have been reconciled already. You'll want to check on your Chart of Accounts so we can verify it. We can see the reconciled transaction if it has R on it.
If this is the case, you don't need to match the downloaded transactions. Instead, you can exclude them. Simply check the tickbox beside the Date. Then, click on the Batch actions drop-down and select Exclude Selected.
I've added these articles for your reference on how to manage downloaded bank transactions:

I'll be here if you have additional concerns. Wishing you all the best!
